GARrTBUCK.

Specification of Letters Patent.

To all whom 2'25 may concern Be it known that I ALnnn'r J. MOCAULEY, a citizen of the llnited States, residing at St. Louis, Missouri, have invented'a certain new and useful Improvement in Car-Trucks, of which thetollowing is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, in whichthefeatures of my invention; Fig. 2 is a horizontal section taken approximately on line 22, Fig. 1; Fig. Sis a view. similar to Fig. 1, illustrating a modification: Fig. 4 is a vertical section taken approximately on line 14, Fig. E; Fig. 5 is a view similar to Fig. 1 illustrating a further modification: and Fig. 6 is a vertical section taken approximately online (i6, Fig. 5. v

This invention relates to improvements in car trucks of the lateral motion type, one of the ob ects being to produce a truck of this character in whlch the seats for the bolster springs are supported by movable. members that allow said spring-seats to move 'lreely so as to permit the bolster to move. laterally with respect to the truck frame. In the preferred form of my invention the spring seats move laterally with the bolster and in this respect they operate very similar to the ordinary swing motion spring seats. however' the swing motion spring seats are connected'to the truck frame by pivot pins, while the spring seats of my invention have hangers which ride. on rockers or rollers. The rollers are mounted on curved or inclined s ats so as to move freely in response to movements "of the bolster and return to normal position after the force causing such movement has ceased. In addition to allowing the bolster to move l'reely in response to movements of the car body. this lateral motion truck is constructed to allow the bolster and spring seats to be very easily re moved from the truck frame. l urthermore the ordinary swing motion truck has pivot pins which inustatrictionally engage oscillating hangers carrying the entire weight ot the car body, and this obviously undesirable I senger car trucks, and locomotive trucks, may be equipped with the lateral motion elements set forth in the claims.

A, designates a'portion of a truck frame which is shown merely to illustrate the function of the lateral .motion devices, said truck frame having a bolster receiving opening 1, the side walls of which are preferably formed by columns 2. The columns shown in Fig. 1 and Fig. 2 are oli'set to provide \seats for rollers 3 or other movable memhers adapted to rock in response to movements of thebolster. v

l designates a spring seat. provided with hangers 5 having extensions 6 at their upper ends whiclroverlap and rest upon the top faces of the rollers 3. The hanger exten sions are preferably shaped to form pockets for thereception of the rollers, and the side walls 7 of said pockets constitute abutments for limiting the movement of the spring seat. said walls or abutments 7 being normally separated from the columns as seen in Fig. 2.

A bolster B is mounted on springs 8 sup ported by the spring seat l. The usual lugs or column guides'tl on the bolster are interlocked with or otherwise suitably fittedto lugs 10 on the hangers freight car truck of the type shown will of eoui'se require two sets oi the elements seen in Fig. 1, each end of lhe bolster being interlocked with a pair of the spring seat hangers 5.

From the foregoing it will be understood that the rollers ll allow the bolster li. springs 8 and spring seat -l io move laterally with respect to the ll'llt'k frame. and that suchmovement is limited by the members 7 at theuppercndsotthehangers. .\sthesprmg -seat hangers ride freely on the rollers when the bolstelfllim'es "-laterall the spring seat does not rock like the ordinary pivoted swing motion spring seats. The springs are therel'ore n t distorted by an unequally distributed compression such as they would receive it carried by a roclting spring seat 'lrictionally engaged with pivot pins.

ln removing the bolster. the lirst step is to remove the springs h. then allowing the bol ter to drop to a point below the lugs 10 on the hangers 5. and thereafter passing the bolster through the space between said hangers. .\l'ter the removal f the bolster. the spring scat may be removed by lil'ting it to disengage the roller [)titltvls from the truck frame, and then passing said pockets .Iatented May 28,1912. Application filed December 18, 1911. Serial No. 666.545.

seat movement is limited by lugs 13 onthe through the enlarged upper portion'of the bolster receiving opening. 1 The bolster 13 shown in 'has column guides 10" adapted to engage 4? having curved extensions 14 fitted to'. 20

columns 2'! on'the truck frame 'Ilhe springs su porting this bolster are mounted on bottom face of said seat. I Fig. 5 and Fig. 6 illustrate a spring seat hangers 5". ,The'hangers are provided with if curvedfaces which rest on rollers 1 3", said rollers being supported by curved seats on the truck frame. a v 7 Having thus'described the invention, what is claimed as new and desired to be secured;

by Letters Patent is p I 1. A car truck having a frame, rollers onsaid frame, and a spring seat having hangers which rest on said rollers.

- 2. A cart-ruck Fig. 3 and Fig. gt;

signature in the this 15th day of ALBERT J, ooaULEr;

having-a frame, rollerson said frame, and a spring seat having hangers which overlap and rest on the top faces of said rollers. r p

3. A cartruck having a tram movable spring seat supports on'said fram a spring seat provided with hangers Whic are carried by said movable springsea supports, springs on said spring seat, an mounted on said springs, said bolster being fitted to said spring seat hangers.

- 4. A car truck having a frame, rollers .on

a bolster i said'frame, a spring seat provide d with hangers which rest on'said rollers, springs on said springs, said bolster being fitted to said spring seat hangers. i

5. A car truck having: a sald frame, a spring seat prov ded with hangerslwhlch rest on said rollers, springs on said spring seat, and bolster mounted on said springseat, and a bolster mounted frame, rollers on 1 r on sald springs, said bolster being interlocked with said spring seat hangers.
